fl '0 all 107mm it may concern:

Be it known that I, Funnel-no Barons, a citizen of the French Republic, residing at Milan, Italy, have invented an Improvement in TeXtile-Fiber-Combing Machines, oi? which the following is a specification.

In all combing machines of the Heilmann type, and those derived from it, where a lap held by a nipper is combed by the passage of the needles of rows of combs mounted on the outer or inner surface of a cylinder or of a cone, or on a flat surface in the mate'ial projecting beyond the said nipper, the combing line is always situated a few millimetres in -li'ront of the nipping line Oil the said combed lap.

It has been sought to bring the first-men tioned line nearer to the second mentioned line by mechanical means, by using steel blades, or brushes, to press the fibres to be combed into the needles of the last needle bars of the circular comb. But the most careful adjustment of the needles close up to the nipper succeeds only in arriving at a combing line which cannot be overstepped owing to the conical shape of the points of the needles.

The combing action can therefore become operative only from the point where the needle becomes cylindrical.

The more the lap can be divided in gradually smaller slivers by using a greater num her of needles to the centimetre, the more. efficacious will be the combing operation.

The limit which has been hitherto attainable is about 30 needles to the centimetr, and the steel points become so weak that they stand only with'diiliculty the work of comband are very liable to break and thus perform the combing badly.

The present invention has for its object to present at the instant of the passage of a finishing needle bar, under the closed nipper, a line of needles, having as it were, twice as many points as the needles of the ordinary needle bar, for the purpose of diminishing the free space between the needles, starting at the extreme points of the needles.

In carrying this invention into ellect, a movable needle bar is caused to approach a fixed needle bar at an acute angle in such a manner that the points of the needles of the two needle bars will be situated on the same line.

The two needle bars are furnished with equal numbers of needles to the centimetre,

192: Serial No. 399,954. the points of the needles of the movable needle bar come very exactly in the middles of the intervals between and at the same height as the points of the needles of the preceding fixed needle bar which is fun nished with for instance 25 needles to the centimetre that are stronger than those having 30 needles to the centimetre, so that in stead of 30 needle points, there will. be 50 needle points which will penetrate the material quite close to the nipping line, and it will be readily perceived that the combing line will have been brought still closer up to the nipping line.

By way of an example of thcpractical execution of this invention the above stated principle is illustrated in the accompanying drawings as, applied to a combing machine of the Heilniann type.

In these drawings Figs. 1 and 2 are sections showing two different positions of the parts of the improved combing machine.

Fig. 8 is a plan showing the position of certain operating parts illustrated in Figs. 1 and 2 with relation to the shaft of the combing cylinder.

tails.

' i'lsshown, the top nipper l and the bottom nip 381 2 upon which the bottom nipper is closed, present the lap to be combed to the comb segment a, and the brush 3 fixed to the top nipper brushes the points of the needles in order to facilitate the entry of the material to be combed, into the needle bars.

The movable needle bar 'I is fixed on a support (3 adapted to rock around the axle 5 inside the shell of the comb segment 4-.

The shaft 10 of the comb cylinder carries two discs 12 to which the comb segment t is fixed. A recess in these discs allows the two rollers 9 to pass, one on the right and the other on the left of the support (5.

In Fig. 1, the roller 9 having slidden over the low concentric portion of the fixed cam 11., being pulled b the torsion spring 13, the support 6 with its adjustin screws 14, bears against the inner part or the shell 4; of the segment, and thereby fixes the dis tance between the needle points I) and 0 in order that the circular brush may be able to enter thoroughly into the needles and thus clean them easily.

In Fig. 2 the roller 9, being mounted on Figs. l 5 and 6 are enlarged views of dethe raised portion of the cam 11 fixed to the training, the movable needle bar 7 has rocked on the axle 5 until its needles 0 present their points at an acute angle at the middles of' the intervals between the needles of the fixed needle bar Y) and on the same line as the points of the said needles Z). The two adjusting screws 8 allow of eiiecting a micrometric adjustment of this approach.

It will be readily perceived that by this arrangement of the parts inaccordance with this invention and as illustrated in Figs. 3 to 6, the lap will be combed twice as much in the position I) c l) of the needles, as by the bar afurnished with the same number of needles.

It is to be understood that any other aril'angement may be adopted, such as for instance, an arrangement wherein the movable needle bar 0 is pulled towards the fixed needle bar Z) by the action of a spring, and is moved away by the action ota cam at the instant when the circular brush ispassing.

and in what manner the same is to be performed, I declare that what I claim is 1. In a "con ib'in'g machine of the Heilmann or similar type, the combination with a fixed needle bar, of a movable needle bar having needles which are arranged at an the instant that the fixed needles enterthe lap to be combed, for the purpose of effecting a more intense combing action by reason of the resulting closer-arrangement of combing needle points.

2; In a combing machine, the combination with a fixed needle bar, of a movable needle bar co-operating with said fixed needle bar,

and means foroperatin'g said movable needle bar to cause the needles carriedthereby to approach the fixed'needles at an acute angle at the times when the fixed needles are entering the lap to be combed.

In testimony whereof I afiix my signature, in presen'ceof two witnesses.
